  <dc:description>&lt;div id="Abs1-section" class="c-article-section"&gt;&lt;div id="Abs1-content" class="c-article-section__content"&gt;&lt;p&gt;Standing dead trees (snags) are recognized for their influence on methane (CH&lt;sub&gt;4&lt;/sub&gt;) cycling in coastal wetlands, yet the biogeochemical processes that control the magnitude and direction of fluxes across the snag-atmosphere interface are not fully elucidated. Herein, we analyzed microbial communities and fluxes at one height from ten snags in a ghost forest wetland. Snag-atmosphere CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;fluxes were highly variable (−&amp;nbsp;0.11–0.51&amp;nbsp;mg CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;m&lt;sup&gt;−2&lt;/sup&gt;&amp;nbsp;h&lt;sup&gt;−1&lt;/sup&gt;). CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;production was measured in three out of ten snags; whereas, CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;consumption was measured in two out of ten snags. Potential CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;production and oxidation in one core from each snag was assayed in vitro. A single core produced CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;under anoxic and oxic conditions, at measured rates of 0.7 and 0.6&amp;nbsp;ng CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;g&lt;sup&gt;−1&lt;/sup&gt;&amp;nbsp;h&lt;sup&gt;−1&lt;/sup&gt;, respectively. Four cores oxidized CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;under oxic conditions, with an average rate of −&amp;nbsp;1.13 ± 0.31&amp;nbsp;ng CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;g&lt;sup&gt;−1&lt;/sup&gt;&amp;nbsp;h&lt;sup&gt;−1&lt;/sup&gt;. Illumina sequencing of the V3/V4 region of the 16S rRNA gene sequence revealed diverse microbial communities and indicated oxidative decomposition of deadwood. Methanogens were present in 20% of the snags, with a mean relative abundance of &amp;lt; 0.0001%. Methanotrophs were identified in all snags, with a mean relative abundance of 2% and represented the sole CH&lt;sub&gt;4&lt;/sub&gt;-cycling communities in 80% of the snags. These data indicate potential for microbial attenuation of CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;emissions across the snag-atmosphere interface in ghost forests. A better understanding of the environmental drivers of snag-associated microbial communities is necessary to forecast the response of CH&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;cycling in coastal ghost forest wetlands to a shifting coastal landscape.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
